T 0 all whom it may concern:

Be it known that I, SAMUEL COFFMAN SAMUELs, a. citizen of the UnitedStates, residing at San Francisco, in the county of San Francisco andState of California, have invented certain new and useful Improvementsin RailroadeTrack Constructions, of which the following is aspecification.

My present invention relates to improvements in track constructions,which will be best understood from the following descrip tion and theannexed drawing of an illustrative embodiment, in which Fig. 1 is avertical longitudinal section on the line 11 of Fig. 2 of a portion of arailroad tie, showing an illustrative form of my invention appliedthereto. Fig. 2 is a plan view of Fig. 1, and Fig. 3 is a section on theline 3-3 of Fig. 2

Like parts have like reference numbers in h se re-1 ie In the form of myinvention which I have chosen for purposes of illustration, the tie is tr-me O an upp r p r 10 and a lower portion 11 with the grain extendinglengthwise of the tie and with the joint between the two sections alsoextending lengthwise of the tieand horizontal.

On the top of the tie is a rail plate 12 extending beyond the verticaledges of the tie and having integral portions 131$ ext n ing o n ard, Pl l to t e S of the tie. On the bottom of the tie is a suppor ng p a aac d to he iey bo t 15, which extend through the two plates and throughholes extending down the sides of h e Th plate l2 ma he fo med w th dg16 t oc te th m l 3, n th bolts m y e u e to clamp the rai to the Plate2 en lth t e y mean .o mm er en a t e ads of h o s 1.5, he x n ed p of hmembe 1 White:- ing over the flange of the rail as shown best inFig. 1.The member 18 may be provided wi dowel p s 191 0 p e e t mem ers 18 fromturning.

The integral portions 13 are connected to the supporting plate 1.4: soas to prevent motion away from the vertical sides ,of the tie, andpreferably this connection will also be me so hat he Plat 1.2 and ay bemoved relatively vertically, and as a mean to his end, .I av p v d d h ial mem rs 3 wi h a p ura i y .of mois Serial Ne. 624,350.

tions 20 on the lower end of each of the integral portions 13, whichprojections extend through corresponding openings in the plate 14, allof the projections 20 being of sulficient length to permit the plates 12and 14 to approach each other before the solid portion of the integralportions 13 cont act with h Pla e 4:.- i

In order to transmit the weight and force applied to the rail R by themoving trains tothe plate 14:, I insert between the sides of the tie andtheintegral portions 13 blo cks 21 of wood, with the grain thereofvertical, these blocks being of sufiicient length so that the weight onthe plate 12 will be trans mitted through the blocks 21 to thesupporting plate 14. It will be understood that the plate 14L will reston the ballast of the roadbed so that any weight transmitted through theblecks 21 Will not be applied to the tie Pr per a the fw ha the tie Pr pwill be relieved of a corresponding amount of pressure which wouldotherwise tend to crush it. The plate may be provided it Pro ecti ns 2 fIt will be noted that the integral portions 13, by their connections tothe top and boton plates 2 a d y their a with-the sides of the blocks 21will bind the tie laterally to prevent its being crushed and forced outlaterally. Preferably, when the-tie up of the two pieces. 10 and 11, Iwill apply to the tie additional members to prevent the crushing of thetie, and to end I may provide a plate 23 having .dc w' rd 'p ittt ns anme a P tions 24 in'contact with the sides of the tie, th intt a membe :1xtend n r u hQles. in a bottom l e v th i h ustre v farm co stit e aportion o e upp r n Pla .4, h h it Will b un too th t; a epa a P at m hPr ide forth is purpose. bolt extends through Th ie a ou h pla e 23 d th.e f rei d h bo tom p e- When the rail B is on a curve it will besubjected to horizontal pressure, as is well man, a .1 Pr v de a m anfor h ldin the rail anchored to resist this horizontal pressure and toprevent overturning of the rail. To this end provide member 27 having,in the illustrative embodiment, an i e 'thp r t .2 en a d in a h e i hra l Pla 1. we in 1 the te me to fit the side of the rail R, a boss 29on either side of the member 27 being provided to give additional area.The end of the member 27 away from the rail engages, in the illustrativeform, the bolt 26, the member 27 being provided with a slot 30 adaptedto permit the extended end 31 of the member 27 to swing into positionbeneath the nut on the bolt 26. A locking member 32 may be provided,this member having a hole through which the bolt 26 extends, and havinga downwardly projecting portion 33 which extends over the edge of theextended portion 31 of the member 27. In addition, I may provide arecess 331 through which a spike or the like may be driven into the tieto hold the member 27 in position.

In present practice, and as is well known, the constant blows of themoving train will cause a crushing or wear in the tie beneath the trackplate 12, and when this wear has proceeded sufficiently far, the tie iswithdrawn and a new tie substituted for it, although a very considerableportion of the discarded tie is not damaged. By my invention two ofthese discarded ties may be sawn longitudinally and the undamagedportions of the discarded ties be put together to form the portions 10and 11, thereby saving one tie and by using the arrangement which I havedescribed, these two p01"- tions may be held together to function aseffectively as the original solid tie. The metal members which surroundthe tie and carry the weight on the rail R will so distribute the loadthat the two-piece tie will have sufficient strength and moreover willbe protected against the crushing blows delivered to the rail R. It willbe-understood, however, that my arrangement may be applied to a solidtie. a

It will also be understood that the arrangement which I have illustratedis merely one form of my invention and that the embodiment thereof maybe widely varied. 7 It will also be understood that some parts of myinvention may be used without other parts. y g

By using the relatively thin blocks 21 at either side of the tie, all ora greatportion of the weight and the force of the blows on the rail Rwill be transmitted lengthwise of the grain of the wood, instead ofcrosswise thereof, as inthe usual tie. As is well known, wood has a muchgreater resistance to crushing when the force is applied-endwise of thegrain than when applled crosswise, so that, with my construction, thereis little tendency for the wood to be crushed or for the plate to beworn into the side of the tie.

By fitting the end of the member 27 beneath the head of the rail as wellas against the side, the side thrust in the rail which would tend toupset it, is more completely resisted, such upsetting motion beingtransmitted directly to the plate 12 and furthermore being resisted bythe other end of the member 27 through its connection to the tie.

By providing the form of connection between the plates 12 and 14, whichI have described, it will be understood that the plate 12 may sink intothe tie without interfering' with the operation of the integral portions13 and 24 to sustain the sides of the tie, the bolts 15 and 26 beingtightened up as required, and the projections 20 and 25 sliding throughthe corresponding openings in the plate 14 to permit this adjustment.

The member 27 may be connected to the rail plate 12 in any of anumber ofways and, if desired, may be made integral therewith.
